Specification of Letters Patent.

Application filed June 5. 1906 Serial No, 320.262.

To all whom at may concern:

Be itknown that I, OTTO S. BEYER, a citizen of the United States ofAmerica, and a resident ofEast Rutherford, Bergen county,

New Jersey, have invented certain new and useful Improvements inTransmission Mechamsm, of which the following is a specification. 9

The present invention relates generally to transmission mechanism, andhas more par- .ticularly reference to mechanism for driving a pluralityof members at differential speeds. I The object of the invention is .toproduce a compact and attractive structure, less bulky and complicatedtheir devices heretofore used for this purpose, and the im rovementresides chiefly in mounting a p urality of shafts,one within the otherand in providing suitable differential transmission-mechanism inconnection therewith.

The invention further consists in other features of construction,combination of parts,

and arrangement of elements more fully hereinafter described.

In the accompanying drawings, the invention has been embodieddn aconcrete and preferred form, shown applied to aseaming machine, but theparticular means used to eflect the various improvements maybe variedwithout departing from the spirit of the invention.

In the said drawings: Figure 1' is a side elevation of a machineembodying the invention, shown partly in section. Fig. 2 is a sectionaldetail view of the transmission mechanism shown in Fig. 1. Fig. 3 is atransverse sectional view on line 3-3 of Fig. 2.

Similar characters of reference indicate corresponding parts in thedifferent views.

1 indicates a framework of any suitable construction for properlysupporting the parts.

2 is the seamer head and 3 the seaming members.

4 is the chuck or clamp.

5 indicates a plurality of work supporters mounted on the rotatable dial6 in a well known manner. The framework carries a bracket 7- supportinga hollow shaft 8 provid ed with suitable driving means such as thehollow pulley 9 to which motion is imparted by means of the belt 10passing over the idlers 1'1' and receiving its motion from the shaft 12carrying the pulley 13. The shaft 8 is provided with suitable means, inthe prescut instance the cams 14 and 15, for causing the seaming membersto move in and out in the usual manner.

Mounted on the hollow pulley 9 is a con centrically disposed internalgear 16 with which meshes the eccentrically disposed external gear 17.

18 is .a shaft located inside of the shaft 8 and carrying the seamerhead 2. Mounted on this shaft 13 isa concentric member 19 in the presentinstance in the form of a disk, and means are provided whereby this diskor member 19 is driven from the eccentrically disposed external gear 17preferably taking the form ofa link 20 attached to the gear 17 andmember 19 by means of the bolts or studs 21 and 22. .Located inside theshaft 18 is a spindle 23 carrying the chuck or clamp 4, the said spindlebeing supported in the bracket 24 of the framework.

As' previously indicated, the seamer head 2 carries the seaming members3. These seaming members in the present instance consist of the curlingroll 48 and the finishing roll 49. k

The rotation of the pulley 9 causes the rotation of the hollow shaft 8and by this means the rotation of the cams 14 and 15 acting respectivelyon the curling and finishing rolls to move the same successively towardand away from the work. Owing to the fact that the gear 17 is in meshwith the gear 16, motion is further imparted to the shaft 18 and fromthence to the seamer head 2.

The arrangement of the parts in the present instance, is such, however,that the seamer head makes about thirty revolutions to each twenty-ninerevolutions of the cams 14 and 15 whereby the seaming operation will beeffccted properly. It will of course be understood that if the cams 14and 15 on the seamer head are rotated at the same speed as the seamerhead, no effect. would be produced inasmuch as the said seaming memberstravel around with the said seamer head. The difference in speed betweenthe cams 14 and 15 noted here need not of course be followed exactly,but used. only for the sake of illustration.

lYhat is claimed is.

l. The combination of two shafts arranged concentrically one within theother, driving means on the outer shaft an internal gear moving with thesaid outer shaft, an eccentrically mounted external gear meshing withwith the internal gear, a concentric member the internal gear, aconcentric member on 011 the inner shaft, and a loose, connection theinner shaft, and means for driving the between the eccentricallydisposed gear and said concentric member from the said eccenthe saidconcentric member.
